Whole-brain cholinergic modulation following computerized cognitive training in healthy older adults: a [18F]FEOBV PET study.

Why it matters

Cholinergic decline is a hallmark of cognitive aging, yet scalable interventions to support cholinergic function are lacking. This trial demonstrates that a widely available, non-pharmacological cognitive training program can increase cholinergic terminal density in key attentional and executive regions, suggesting a neurobiological mechanism for cognitive resilience that may inform preventive strategies in aging populations.
